It's almost perfect except for two things. MFT doesn't like either of my USB sticks - rather, it liked one for a couple of days and told me it was unsupported ever since.
And sometimes when I use IA to unlock the driver's door (by holding the handle and black square), it chrips as though I was trying to confirm it was locked. I've actually no idea how it would know whether I wanted to unlock or confirm it was locked! It gets it right most of the time.
